DETAILED DESCRIPTION

[0027] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. Example 1

[0028] like Figure 1-Figure 7As shown, a metal wire processing and straightening machine includes a processing table 1, a control module 2 is installed on the left side of the processing table 1, and a plurality of mounting seats 3 are arranged on the upper side of the processing table 1, all of which are distributed at equal intervals, and the mounting seats 3 are rotatably connected to a fixed disk 4, and the interior of the fixed disk 4 is provided with support rods 5 evenly distributed in the circumference, and extrusion balls 6 are installed on the opposite sides of all support rods 5 on the same fixed disk 4. For the convenience of subsequent description, all the extrusion balls 6 on a fixed disk 4 are divided into a group, and the extrusion balls 6 rotate freely on adjacent support rods 5. The extrusion balls 6 are used to extrude the wire, and the gaps between different groups of extrusion balls 6 gradually decrease from right to left (the extrusion pressure on the wire gradually increases), thereby realizing the straightening operation of the wire, and applying circumferential multi-point extrusion pressure to the wire through the circumferentially distributed extrusion balls 6, so that the force on the wire is more uniform. A driving module is installed on the upper side of the processing table 1, and the driving module is used to drive all the fixed disks 4 to rotate. In this embodiment, the driving module is composed of a motor, a transmission shaft, a plurality of driving gears and a plurality of driving gear rings. A feeding module 9 is provided on the right side of the processing table 1, and the feeding module 9 is used to convey the wire. The feeding module 9 and the driving module are both electrically connected to the control module 2. The control module 2 is used to control the opening and closing of the motor in the driving module, and control the opening and closing of the feeding module 9. A multi-axis robot arm and a cutting device that apply tension to the wire are provided on the left side of the processing table 1. The multi-axis robot arm drives the wire to move to the left, and the cutting device cuts the wire (not shown in the figure); in this embodiment, the mounting seat 3 and the processing table 1 are fixedly connected to the support rod 5 and the fixed disk 4; the feeding module 9 is an existing structure, mainly composed of a support frame, an electric shaft and a wire roller.

[0029] Working principle:

[0030] When straightening the wire, the operator first passes the end of the wire (the wire to be processed) on the feeding module 9 through the rightmost group of squeezing balls 6, and then passes it through each group of squeezing balls 6 from right to left in turn, until the wire passes through all the squeezing balls 6. The control module 2 controls the multi-axis robotic arm to clamp the end of the wire. At this time, all the squeezing balls 6 jointly apply circumferential and multi-point squeezing force to the wire they contact, and use the squeezing balls 6 to contact the wire to reduce the shear force on the wire and reduce the probability of wire breakage.

[0031] After the end of the wire is fixed, the control module 2 turns on the driving module, and the driving module drives all the fixed disks 4 to rotate, and the fixed disks 4 drive the support rods 5 thereon to rotate, and the support rods 5 drive the squeezing balls 6 to rotate. During the rotation of the squeezing balls 6, a circumferential and continuous squeezing force is applied to the wire (from a point to a line).

[0032] After the driving module is turned on, the control module 2 controls the multi-axis robot arm and the feeding module 9 to work. The multi-axis robot arm pulls the wire, causing the wire to gradually move from right to left. At the same time, the wire is released from the feeding module 9. During the movement of the wire, all the squeezing balls 6 apply axial and continuous squeezing force to the wire (from line to surface), thereby deforming the wire into a straight state. After the wire passes through the leftmost fixed disk 4, it indicates that the processing is completed. After the wire moves to the target distance, the control module 2 controls the cutting equipment to work and cuts the wire. After that, the multi-axis robot arm clamps the end of the wire to be processed again, pulls the wire, and then cuts the wire again. This is repeated until the wire on the feeding module 9 is processed.

[0033] When the wire is straightened, the control module 2 turns off all electrical components. Example 2

[0034] On the basis of Example 1, Figures 1-6 As shown, the drive module includes a drive motor 7, which is fixed to the processing table 1. The control module 2 is used to control the opening and closing of the drive motor 7. The output shaft of the drive motor 7 is fixed to the spline rod 8. A spur gear 801 is rotatably connected in the mounting seat 3. The spur gear 801 is spline-connected to the spline rod 8. A spur gear ring 802 is fixed to the fixed plate 4. The spur gear ring 802 is engaged with the adjacent spur gear 801. The mounting seat 3 is connected to the processing table 1 by bolts.

[0035] The above setting can be realized. All the parts on a mounting seat 3 together constitute a straightening module. The position and quantity of all mounting seats 3 can be adjusted. The operator can adjust the distribution and quantity of the straightening modules according to the actual properties of the wire. For example, if the wire is elastic, the number of straightening modules needs to be increased and the distance between two adjacent straightening modules needs to be shortened to ensure sufficient squeezing of the wire and reduce the degree of rebound of the wire. If one of the parts is damaged, the straightening module can be replaced alone without affecting the normal operation of the remaining straightening modules.

[0036] Most of the existing straightening devices are composed of multiple rotating squeezing rollers, and the squeezing rollers are distributed laterally (the axis of the squeezing roller is not perpendicular to the axis of the wire in the same plane), which results in a large space required for this method. Based on this problem, the present application sets the axis of the fixed disk 4 to coincide with the axis of the wire, changes the way the wire is squeezed, saves the space occupied by the device, and can also adjust the position of all straightening modules according to the actual operating space, so that the device can make full use of the operating space. Example 3

[0037] Before working, the existing straightening device will adjust the distance between all straightening rollers according to the type of wire to ensure the straightening effect of the wire. However, during the straightening process, the position of the straightening rollers is fixed. Since the bending degree and bending shape of the wire are uncontrollable, the greater the bending degree of the wire, the greater the extrusion force exerted by the straightening rollers on the wire. At this time, excessive extrusion force will cause excessive stress inside the wire, which will lead to local over-stretching or compression, causing cracks or surface damage, affecting the subsequent use of the wire. To reduce the occurrence of this situation, the following are the specific measures:

[0038] On the basis of Example 2, Figure 3-Figure 7 As shown, the fixed disk 4 is rotatably connected to a fixed ring 21, and a circumferentially evenly distributed limit frame 22 is fixed to the inner side of the fixed ring 21. The limit frame 22 corresponds to the support rod 5 one by one, and the support rod 5 is slidably connected to the fixed disk 4. The limit frame 22 is provided with a guide hole. The shape of the guide hole is approximately triangular, and its three sides are arcs. The guide hole of the limit frame 22 is used to limit the adjacent support rods 5. The guide hole of the limit frame 22 has a first guide part 2201 and a second guide part 2202. The distance between the first guide part 2201 and the second guide part 2202 gradually increases from close to the corresponding support rod 5 to the other side. The shape of the guide hole of the limit frame 22 is set to provide movement space for the support rod 5. At the same time, the first guide part 2201 limits the maximum sliding distance of the support rod 5, thereby controlling the maximum distance between all the extrusion balls 6 on a straightening module, thereby controlling the adaptability range of the straightening module to the bending degree of the wire.

[0039] like Figure 2 、 Figure 3 and Figure 5 As shown, the fixed ring 21 is fixed with a number of guide blocks 31, and the fixed disk 4 is provided with sliding grooves with the same number as the guide blocks 31. The guide blocks 31 slide in the adjacent sliding grooves on the fixed disk 4. The guide blocks 31 are threadedly connected with threaded push rods 32, and the threaded push rods 32 are in extrusion contact with the fixed disk 4; the sliding grooves of the fixed disk 4 are set on the scale line to indicate the distance moved by the guide blocks 31.

[0040] Working principle:

[0041] Before straightening the wire, the operator first adjusts the movable space of all support rods 5 according to the shape of the wire. Taking the adjustment of the right straightening module as an example, the operator rotates the threaded push rod 32 to reduce the squeezing force of the threaded push rod 32 on the fixed plate 4 until the guide block 31 can slide along the adjacent slide groove on the fixed plate 4. The operator stops rotating the threaded push rod 32. After that, the operator rotates the guide block 31 counterclockwise according to the scale line on the fixed plate 4 (to Figure 3), the guide block 31 drives the fixed ring 21, and the fixed ring 21 drives the limit frame 22 thereon to rotate synchronously. During this process, the limit frame 22 and the adjacent support rod 5 move relative to each other, and the first guide portion 2201 of the limit frame 22 gradually loses contact with the adjacent support rod 5, and the distance between the two gradually increases until the middle of the guide block 31 moves to the specified scale line position, and the guide block 31 stops rotating.

[0042] After stopping the rotation of the guide block 31, the operator rotates the threaded push rod 32 in the opposite direction to gradually increase the squeezing force of the threaded push rod 32 on the fixed disk 4 until the threaded push rod 32 can no longer move. The fixation between the guide block 31 and the fixed disk 4 is completed, and the adjustment of the right straightening module is completed. After that, the operator repeats the above operation to adjust the movable space of the support rod 5 in the remaining straightening modules. During this process, the rotation angle of the guide block 31 gradually decreases from right to left, that is, the movable space of the support rod 5 gradually shrinks, thereby ensuring the straightening effect on the wire.

[0043] After the adjustment is completed, the wire straightening operation is started. When the bent part of the wire hits the squeezing ball 6, the squeezing ball 6 is pressed and moves outward. The squeezing ball 6 pushes the support rod 5 to move, and the support rod 5 and the limit frame 22 move relative to each other. In this way, the support rod 5 and the limit frame 22 slide relative to each other to shorten the distance of the wire squeezing, thereby reducing the squeezing force on the bent part of the wire, until the support rod 5 contacts the first guide part 2201 again. The first guide part 2201 limits the support rod 5, so that the support rod 5 squeezes the wire through the squeezing ball 6. Through the above process, the wire is pre-straightened, and the bending defects of the material (such as waves and twists) are preliminarily eliminated. The pre-straightening provides a more uniform deformation basis for subsequent straightening, thereby reducing the difficulty of the final straightening and reducing the occurrence of force concentration on the wire.

[0044] After the wire is straightened, the operator repeats the above operation in reverse to reset all the guide blocks 31 and wait for the next use.

[0045] During the above adjustment process, the operator can consider adjusting the number and position of the straightening modules according to actual needs; since the straightening operation implemented by this device is modular, the operator can adjust different straightening modules to increase the applicability of this device. Example 4

[0046] On the basis of Example 3, Figure 1-Figure 3 、 Figure 5 and Figure 6As shown, the fixed disk 4 is provided with two symmetrically distributed extrusion disks 41, and the extrusion disks 41 are in extrusion contact with all the support rods 5 on the same mounting seat 3; the side of the support rod 5 close to the corresponding extrusion ball 6 is set to a cone shape, and the diameter of the cone part of the support rod 5 gradually increases from the side close to the center of the fixed disk 4 to the other side; the middle part of the extrusion disk 41 is provided with two parallel annular inclined surfaces, and the annular inclined surface on the side of the extrusion disk 41 close to the corresponding extrusion ball 6 is in extrusion contact with the cone surface of the adjacent support rod 5, thereby adjusting the position of the support rod 5, and at the same time the extrusion disk 41 limits the support rod 5, so that the support rod 5 cannot move inward, thereby controlling the minimum distance between all the extrusion balls 6 in the straightening module, so that the device can be applied to different types of wires.

[0047] The annular inclined surface of the squeezing disc 41 away from the corresponding squeezing ball 6 is used to guide the wire, so that the wire can pass through the squeezing disc 41.

[0048] like Figure 3 、 Figure 5 and Figure 6 As shown, the fixed disk 4 is rotatably connected to two threaded rotating rods 51 distributed upper and lower, and the extrusion disk 41 is threadedly connected to the two adjacent threaded rotating rods 51. The threaded rotating rod 51 is used to drive the two extrusion disks 41 on the same mounting seat 3 to move relative to each other. Initially, the distance between the two adjacent extrusion disks 41 is the largest, that is, the distance between all the extrusion balls 6 in a straightening module is the smallest.

[0049] Working principle:

[0050] When straightening the wire, the operator first adjusts the distance between the two adjacent extrusion disks 41 according to the model of the wire. Taking the adjustment of the rightmost straightening module as an example, the operator rotates the two threaded rods 51 at the same time, and the distance between the two extrusion disks 41 gradually decreases. The two extrusion disks 41 jointly squeeze all the support rods 5, so that all the support rods 5 move outward, that is, the distance between all the extrusion balls 6 gradually increases, and then the adapted wire model also gradually increases. When the distance between all the extrusion balls 6 corresponds to the wire model, stop rotating the threaded rod 51. At this time, the adjustment of the extrusion balls 6 is completed, and then the wire straightening operation is started. After the straightening operation is completed, the threaded rod 51 is rotated in the opposite direction to restore the distance between the two extrusion disks 41 to its initial state.

[0051] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge of those skilled in the art without departing from the spirit of the present invention.
